STEEL-INGOT VIOLD.

SPECIFICATION forming part of Letters Patent No. 290,626, dated December Application ledApril 7, 1883. (No model.)

.To all whom t may concern:

Beit known that I, FRANK N EAI. BEAZLE, a resident of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Steel-Ingot Molds; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification. v

My invention relates to molds used in casting steel into ingots, and it consists, particularly, in an improved bottom therefor, which I have hereinafter described and specifically claimed.

In the drawings, Figure lis an inside view, and Fig. 2 an outside View, of my improved mold. Figs. 3 and 4 show the form in general use. Fig. 5 is the removable end piece or bottom; Fig. 6, a top view of the mold. Fig. 7 shows a modification in construction of the bottom. Y

Like letters of reference refer to like parts.

The letters A A represent the two sections of the mold, held together by slip-bands C C', and having an eight-sided bore, G, extending lengthwise through the center to form the ingot.

B is a cylindrical piece of metal shaped in the manner of a tapering plug, having two flat faces, b b. This plug fits into a cylindrical bore, F, in the end of the mold, the bore being made about three-fourths of an inch larger than the bore in the mold for casting the ingots, so that a shoulder, e, will be formed in the wall of the mold as a stop for the end of the plug, which forms aclosed end or bottom for the mold. This end piece is made to fit neatly into the recess provided for it, the lower end projecting slightly below the end of the mold, so that the weight ofthe mold will bear directly on it when standing upright, for the purpose of holding it in its place, by resting the mold upon it during the process of casting the ingots.

The mode of operation is to first clamp the two sections of the mold together by slipping the bands over the outside of the mold. The

mold is then placed upright, with the lower end resting on the end piece. The operator then pours in the molten metal until the mold is full. When the metal is sufficiently cool, the clamps are removed om the body of the mold and the ingot taken out.

The removable end piece can be made eightsided, similar to the bore in the mold; or it can have any other number of sides, it being essential in all cases that the bottom piece be somewhat larger than the bore in the mold for casting the ingot, so there will be no joint in the line of the falling metal. I find the cylindrical-shaped bottom piece to possess the advantage of being placed more readily into the bore or recess in the bottom` of the mold.

In the casting of metals, where it is desirable that a different material should be brought in contact with the molten metal than that of 7c which the mold is made-such as fire-clay or carbonaceous materials of any kind-I make a recess in the upper face of the bottom piece (shown at cin Fig. 7) and fill it in with the desired material. By making the recess larger in the bottom than at the top, it operates to hold the substance firmly in place. Small holes can also be bored in the bottom of the recess in different directions for the same purpose.

Carbonaceous materials or clays of any kind can readily be placed in the end of the mold, by means of the recess in the bottom piece, if such is found desirable in the process of casting the various metals.

Having described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-

The combination, with a sectional mold for casting metal into ingots, of a plug of larger diameter than the bore of the mold, and fitting in a recess in the end of the said mold to form the bottom, substantially as described.

In testimony that I claim the foregoing as my own I hereto affix my signature in presence of two witnesses.
